Differences between the DNA appliance(Vivos) and Homeoblock appliance, will either leave gaps in teeth after treatment?

There are subtle design differences between the two appliances but both are effective to develop dental arches (orthopedic development). These are not the only two arch development appliances either. There are many effective arch development appliances that work well in the right hands.

Good luck!

 Both are similar functional appliances but I find the DNA works best in adults and bicuspid extraction cases.  Homeoblock works great in children.
